Description
The β+--electron-capture decay of 69Se, produced via the 40Ca(32S, 2pn)69Se reaction, has been studied by β-delayed proton and γ-ray emissions using the recoil transport helium jet technique. The established decay scheme for 69Se involves 13 up to now unreported γ emitting levels in 69As. The total proton branching ratio has been measured to be (4.5 +- 1.0) x 10-4. The autocorrelation analysis of the delayed proton spectra indicates a level spacing in agreement with the back shifted Fermi gas model estimates. The Gamow-Teller beta strength distribution has been measured in 95% of the Q/sub β/ window, up to 6.5 MeV excitation energy in 69As
